Opscenter LCM 集群 dse 未启动

Question

我已经通过 Opscenter LCM 配置了一个 Cassandra 集群。当 opscenter LCM 尝试在最后阶段启动 DSE 时，失败并出现以下错误。

}

奇怪的是，如果您手动将 cassandra-env.sh 添加到服务器并将 /tmp 路径放置为 - JVM_OPTS="$JVM_OPTS -Djna.tmpdir=/path_to_directory" 并在服务器上手动启动 DSE，它启动正常。

但是 LCM 出了什么问题？我为新的 /tmp 路径添加了额外的 jvm 选项。

如何在 opscenter LCM 中修复此问题？

注意-它的 DSE 6.0

谢谢

Answer 1

这里是 LCM 开发人员。您的环境有些异常，您没有说明您在手动启动顺序中配置的临时目录。

我认为默认情况下 DSE 可能不支持 tmp 挂载 noexec？您的手动 tmpdir 和 /tmp 之间的挂载选项有区别吗？权限有区别吗？

或者，LCM 的 jvm.options 页面作为 "additional-jvm-options" 列表，您可以向其中添加任意 -D 选项。如果您无法弄清楚是什么环境问题导致了这个问题，您可以告诉 LCM 使用您一直在手动测试的额外选项配置 DSE。
